POLYMER-DISPERSED LIQUID CRYSTAL ELEMENT AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2023/022155

A1

The present invention provides a polymer-dispersed liquid crystal element which is provided with a liquid crystal alignment film that achieves high adhesion between a polymer liquid crystal layer and a base material, while having a high light transmittance in a high transmission state.　A polymer-dispersed liquid crystal element which is provided with: a pair of base materials that are arranged so as to face each other; electrodes that are respectively arranged on surfaces of the pair of base materials, the surfaces facing each other; a light control layer that is arranged between the pair of base materials, while comprising a polymer phase and a liquid crystal phase; and a liquid crystal alignment film that is formed on the electrode arrangement surface of at least one of the pair of base materials. With respect to this polymer-dispersed liquid crystal element, the light control layer is formed by polymerization of a light control layer forming material; the light control layer forming material contains a liquid crystal composition and a polymerizable compound component; and the liquid crystal alignment film is formed of a liquid crystal aligning agent that contains a component (A). (In formula (1), the definition of each symbol is as defined in the description.) (In formula (2), the definition of each symbol is as defined in the description.)
